I recently bought a racquet off the board here --advertised as 4 3/8 but was not (built up to a little bigger than 4 1/2). It was advertised as 4 3/8. I have small hands and refuse to play with grips that are too large. Anyway, I e-mailed the person who admitted that the grip was built up (nice timing). Anyway, he says that I can remove the grip and cut the build up off. I am aware of such things, but is that a normal thing to do or is there a risk that I could harm the frame? THanks in advance.
